Chrome probably gives it back if something else wants it. Computers like using as much RAM as possible. Although I dunno if Chrome should be using more than a couple of gigs or so provided you’ve got less than 10 tabs open.

Think it’s 64 for as well. Confused about what sort of software you’re running on windows 10 that needs 32 bit. That’s only usually for 16bit programs as Windows and X64 has backward compatibility with 32 bit programs.

If it’s like that you’re using the wrong distro, or some really weird hardware. Ubuntu, LM, Fedora and even, usually, debian can be installed & used without ever touching a command line. You’ll need a bit of technical knowledge to dual-boot them but that’s no different to Windows.

Android support, on a non-Google phone, does indeed suck. Custom roms and security updates through apps does mean OS updates are less essential but it’s still shameful how rarely a large OEM like samsung updates phones past a version or so ahead of what they originally got.

Do it, the only way to be completely safe from online attacks is to be offline, the next best thing is to update whenever you can. If you’re concerned about speed/features check before you update but do security ones (on android at least) straight away.
